Abstract

An overall three-dimensional finite element model has been established to simulate the high pressure water conveyance tunnel lining strengthened with steel-bonded reinforcement method. This model is used to analyze the mechanical characteristics of steel plate pasted on the inner surface of the lining concrete. Influence of the ratio of viscose’s elasticity modulus to thickness on the stress transferred from steel plate to concrete is analyzed. The hoop stress of lining concrete and steel plate under the conditions of different ratios of viscose’s elasticity modulus to thickness is also studied. The analyses show that the internal water pressure undertaken by steel plate decreases and the internal water pressure undertaken by concrete increases when the ratio of viscose’s elasticity modulus to thickness (E/T) increases. Using the viscose with smaller ratios of elasticity modulus to thickness can increase the utilization of steel plate and improve the stress condition of lining concrete. Changes in the ratio of viscose’s elasticity modulus to thickness has a great influence on the stress of steel plate and concrete lining when E/T is less than or equal to 10 N/mm3, and changes in the ratio of viscose’s elasticity modulus to thickness has a small influence on the stress of steel plate and concrete lining when E/T is greater than 10 N/mm3. In the design of steel bonded structure, we suggest using the viscose which the ratio of elastic modulus to thickness is less than 10 N/mm3.
